Description

Technical Field

[0001] This utility model relates to the field of air release valve technology, and in particular to an automatic air release valve for a water pump with anti-clogging function. Background Technology

[0002] As a key component of booster equipment, water pumps inevitably contain gas during liquid pressurization. During equipment commissioning and water supply, gas in the pipeline eventually accumulates in the water pump, causing it to run dry. During normal use, scattered gas in the pipeline system accumulates in the water pump, causing pitting corrosion on the impeller and affecting its service life. When the water pump needs a certain suction head to start, it is difficult to draw liquid into the pump, making it unusable. Therefore, automatic air vents are often used to remove air from the water pump.

[0003] Existing automatic air vent valves for water pumps typically involve mounting the valve body on the water pump. When the gas pressure in the pump exceeds the system pressure, the float descends, causing the valve stem to move downwards, opening the valve and allowing gas to be continuously released through the vent pipe. When the gas pressure falls below the system pressure, the float rises, causing the valve stem to move upwards, closing the valve and thus achieving automatic air venting of the water pump.

[0004] However, since the valve body is directly exposed, dust and impurities from the outside may fall into the vent pipe during long-term use, causing blockage inside the vent pipe and affecting the normal exhaust of the valve body. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic air vent valve for water pumps with anti-clogging function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic air vent valve for a water pump with anti-clogging function, comprising a valve body, an air outlet pipe provided on one side of the valve body, a dustproof device provided on one side of the air outlet pipe, the dustproof device comprising a circular cover and a circular tube, a connecting device provided between the circular cover and the air outlet pipe, the circular cover being fitted onto the surface of the air outlet pipe, a circular plate being fixedly connected to one side of the circular tube, the surface size and shape of the circular plate being adapted to the inner wall size and shape of the circular cover, a spring being fitted onto the surface of the circular tube, one end of the spring being fixedly connected to the circular tube, and the other end of the spring being fixedly connected to the inner wall of the circular cover.

[0007] The effect achieved by the above components is as follows: By setting up a dustproof device, the circular cover is first assembled with the exhaust pipe through a connecting device, so that the circular cover fits over the surface of the exhaust pipe. The circular cover, together with the circular plate, completely encloses the exhaust port of the exhaust pipe and intercepts external dust. When the exhaust pipe exhausts air, the gas blows the circular plate, pushing it away from the inside of the circular cover. When the circular plate moves away from the inside of the circular cover, the gas is discharged through the gap between the circular cover and the circular plate. After the exhaust pipe has finished exhausting air, the spring's extension and contraction cause the spring to pull... The moving circular tube moves closer to the inside of the circular cover, causing the circular plate to move closer to the inside of the circular cover. When the circular plate returns to its original position inside the circular cover, it works with the circular cover to wrap around the opening of the exhaust pipe again and continue to intercept external dust, thereby achieving dust protection for the exhaust pipe. This reduces the possibility of external dust and impurities falling into the exhaust pipe during long-term use, causing blockage and affecting the normal exhaust of the valve body. It also improves the cleanliness and dustproof effect of the exhaust pipe when it is not in use.

[0008] Preferably, a positioning rod is fixedly connected to the inner wall of the circular cover, and the surface of the positioning rod is slidably connected to the inner wall of the circular tube.

[0009] The effect achieved by the above components is that by setting a positioning rod, the positioning rod can be located inside the round tube to limit the round tube and the round plate, thereby reducing the shaking of the round tube and the round plate during use.

[0010] Preferably, a sealing plate is fixedly connected to one side of the circular plate, and the surface of the sealing plate is annular.

[0011] The effect achieved by the above components is as follows: by setting the sealing plate, the sealing plate can seal the gap between the circular plate and the circular cover, improve the sealing performance between the circular plate and the circular cover, and further improve the interception effect of external dust and impurities.

[0012] Preferably, the surface of the dome is fixedly connected with a plurality of reinforcing ribs, which are arranged at equal intervals.

[0013] The effect achieved by the above-mentioned components is that by setting reinforcing ribs, the strength of the dome can be increased, reducing the impact of external objects on the dome during use, thus preventing deformation or damage to the dome.

[0014] Preferably, an auxiliary plate is fixedly connected to one side of the dome, and the surface of the auxiliary plate is rectangular.

[0015] The effect achieved by the above components is that by setting up the auxiliary plate, the auxiliary plate can provide a point of leverage for personnel, allowing personnel to easily move the circular cover by manually moving the auxiliary plate.

[0016] Preferably, the connecting device includes a cylinder, which is fixedly sleeved on the surface of the air outlet pipe. A threaded hole is opened on one side of the cylinder, and a bolt is threadedly connected to the inner wall of the threaded hole. A circular hole ring is fixedly connected to one side of the circular cover. The surface of the circular hole ring is slidably connected to the inner wall of the cylinder. The size and shape of the bolt surface are adapted to the size and shape of the inner wall of the circular hole ring.

[0017] The effect achieved by the above components is as follows: by setting up a connecting device, the round cover is first moved manually, causing the round cover to move the round hole ring. When the round hole ring moves to the position of being inserted into the cylinder, both the round cover and the round hole ring are fitted onto the surface of the air outlet pipe, so that the inner wall of the round hole ring coincides with the inner wall of the threaded hole. At this time, the bolt is turned by a tool, so that the bolt is turned into the position of the threaded hole and the round hole ring to fix the position of the round hole ring and the round cover, thereby completing the assembly of the dustproof device and the air outlet pipe. At the same time, the dustproof device can be disassembled later, which improves the flexibility of use of the dustproof device and the convenience of later maintenance.

[0018] Preferably, a plurality of reinforcing blocks are fixedly connected to one side of the cylinder, and the surface of the reinforcing blocks is trapezoidal.

[0019] The effect achieved by the above-mentioned components is that by setting up the reinforcing blocks, the reinforcing blocks can provide auxiliary support and reinforcement to the side of the cylinder close to the cover, reducing the possibility of deformation or breakage of the side of the cylinder close to the cover during use.

[0020] Preferably, a limiting groove is formed on one side of the circular ring, and a limiting block is fixedly connected to the inner wall of the cylinder, wherein the surface size and shape of the limiting block are adapted to the size and shape of the inner wall of the limiting groove.

[0021] The effect achieved by the above components is as follows: by setting the limiting block and the limiting groove, the limiting block can be moved to the position of the circular hole ring inserted into the limiting groove to calibrate the position, so that the inner wall of the circular hole ring can quickly coincide with the inner wall of the threaded hole, which facilitates the quick screwing in of the bolt.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, by setting a dustproof device, the outlet of the vent pipe can be completely covered and external dust and impurities can be intercepted. This reduces the possibility of external dust and impurities falling into the vent pipe during long-term use, causing blockage inside the vent pipe and affecting the normal exhaust of the valve body. It also improves the cleanliness and dustproof effect of the vent pipe when it is not in use. Attached Figure Description

Detailed Implementation

[0029] Reference Figure 1-4 As shown, this embodiment discloses an automatic air vent valve for a water pump with anti-clogging function, including a valve body 1. An air outlet pipe 2 is provided on one side of the valve body 1, and a dustproof device 3 is provided on one side of the air outlet pipe 2. The dustproof device 3 includes a circular cover 31 and a circular tube 35. A connecting device 4 is provided between the circular cover 31 and the air outlet pipe 2. The circular cover 31 is fitted onto the surface of the air outlet pipe 2. A circular plate 37 is fixedly connected to one side of the circular tube 35. The size and shape of the surface of the circular plate 37 are adapted to the size and shape of the inner wall of the circular cover 31. A spring 36 is fitted onto the surface of the circular tube 35. One end of the spring 36 is fixedly connected to the circular tube 35, and the other end of the spring 36 is fixedly connected to the inner wall of the circular cover 31. By setting the dustproof device 3, the circular cover 31 is first assembled with the air outlet pipe 2 through the connecting device 4, so that the circular cover 31 fits onto the surface of the air outlet pipe 2. This allows the circular cover 31, together with the circular plate 37, to completely enclose the exhaust port of the air outlet pipe 2 and intercept external dust. When the air outlet pipe 2 exhausts... When the gas blows, it pushes the circular plate 37 away from the inside of the circular cover 31. When the circular plate 37 moves away from the inside of the circular cover 31, the gas is discharged through the gap between the circular cover 31 and the circular plate 37. After the exhaust pipe 2 has finished exhausting, under the extension and contraction of the spring 36, the spring 36 pulls the circular tube 35 towards the inside of the circular cover 31, causing the circular tube 35 to drive the circular plate 37 towards the inside of the circular cover 31. When the circular plate 37 returns to its original position and enters the inside of the circular cover 31, the circular plate 37, together with the circular cover 31, once again covers the opening of the exhaust pipe 2 and continues to intercept external dust, thereby achieving dust protection for the exhaust pipe 2. This reduces the possibility of external dust and impurities falling into the exhaust pipe 2 during long-term use, causing blockage inside the exhaust pipe 2 and affecting the normal exhaust of the valve body 1. It also improves the cleanliness and dustproof effect of the exhaust pipe 2 when it is idle.

[0030] Reference Figure 2 and Figure 3 As shown, this embodiment discloses that a positioning rod 32 is fixedly connected to the inner wall of the circular cover 31. The surface of the positioning rod 32 is slidably connected to the inner wall of the circular tube 35. By setting the positioning rod 32, the positioning rod 32 can be located inside the circular tube 35 to limit the circular tube 35 and the circular plate 37, reducing the shaking of the circular tube 35 and the circular plate 37 during use. A sealing plate 38 is fixedly connected to one side of the circular plate 37. The surface of the sealing plate 38 is annular. By setting the sealing plate 38, the sealing plate 38 can seal the gap between the circular plate 37 and the circular cover 31, improving the sealing performance between the circular plate 37 and the circular cover 31, and further improving the interception effect of external dust and impurities.

[0031] Reference Figure 2 and Figure 3 As shown in the figure, this embodiment discloses that the surface of the dome 31 is fixedly connected with a plurality of reinforcing ribs 33, which are arranged at equal intervals. By setting the reinforcing ribs 33, the strength of the dome 31 can be increased, and the dome 31 can be reduced from being deformed or damaged by collisions with external objects during use. An auxiliary plate 34 is fixedly connected to one side of the dome 31. The surface of the auxiliary plate 34 is rectangular. By setting the auxiliary plate 34, the auxiliary plate 34 can provide a point of leverage for personnel, so that personnel can move the dome 31 conveniently by manually moving the auxiliary plate 34.

[0032] Reference Figure 3 and Figure 4 As shown, this embodiment discloses a connecting device 4 including a cylinder 41, which is fixedly sleeved on the surface of the air outlet pipe 2. A threaded hole 42 is opened on one side of the cylinder 41, and a bolt 43 is threadedly connected to the inner wall of the threaded hole 42. A circular hole ring 46 is fixedly connected to one side of the circular cover 31. The surface of the circular hole ring 46 is slidably connected to the inner wall of the cylinder 41. The size and shape of the bolt 43 are adapted to the size and shape of the inner wall of the circular hole ring 46. By setting the connecting device 4, the circular cover 31 is first manually moved, so that the circular cover 31 drives the circular hole ring 46 to move. When the circular ring 46 moves to the position inside the inserted cylinder 41, both the circular cover 31 and the circular ring 46 are fitted onto the surface of the air outlet pipe 2, so that the inner wall of the circular ring 46 coincides with the inner wall of the threaded hole 42. At this time, the bolt 43 is rotated by a tool, so that the bolt 43 is turned into the position inside the threaded hole 42 and the circular ring 46 to fix the circular ring 46 and the circular cover 31 in position, thereby completing the assembly of the dustproof device 3 and the air outlet pipe 2. At the same time, the dustproof device 3 can be disassembled later, which improves the flexibility of use of the dustproof device 3 and the convenience of later maintenance.

[0033] Reference Figure 3 and Figure 4As shown, this embodiment discloses that a plurality of reinforcing blocks 45 are fixedly connected to one side of the cylinder 41. The surface of the reinforcing blocks 45 is trapezoidal. By setting the reinforcing blocks 45, the reinforcing blocks 45 can provide auxiliary support and reinforcement to the side of the cylinder 41 close to the circular cover 31, reducing the possibility of deformation or breakage of the side of the cylinder 41 close to the circular cover 31 during use. A limiting groove 47 is opened on one side of the circular hole ring 46. A limiting block 44 is fixedly connected to the inner wall of the cylinder 41. The surface size and shape of the limiting block 44 are adapted to the size and shape of the inner wall of the limiting groove 47. By setting the limiting block 44 and the limiting groove 47, the limiting block 44 can move to the position of inserting into the limiting groove 47 to calibrate the position of the circular hole ring 46, so that the inner wall of the circular hole ring 46 can quickly overlap with the inner wall of the threaded hole 42, which facilitates the quick screwing in of the bolt 43.

[0034] Working principle: First, valve body 1 is installed on the water pump. When the gas pressure in the water pump is greater than the system pressure, the float will fall and drive the valve stem to move downward, opening the valve port and continuously venting the gas through the vent pipe 2. When the gas pressure is lower than the system pressure, the float will rise and drive the valve stem to move upward, closing the valve port, thereby achieving automatic venting of the water pump.

[0035] First, manually move the circular cover 31, causing it to move the circular ring 46. When the circular ring 46 moves to the position inside the inserted cylinder 41, both the circular cover 31 and the circular ring 46 are fitted onto the surface of the exhaust pipe 2, making the inner wall of the circular ring 46 coincide with the inner wall of the threaded hole 42. At this time, use a tool to rotate the bolt 43, causing the bolt 43 to turn into the position inside the threaded hole 42 and the circular ring 46, fixing the circular ring 46 and the circular cover 31 in place, thus completing the assembly of the dustproof device 3 and the exhaust pipe 2. At this time, the circular cover 31 is fitted onto the surface of the exhaust pipe 2, so that the circular cover 31, together with the circular plate 37, completely covers the exhaust port of the exhaust pipe 2 and intercepts external dust. When the exhaust pipe 2 exhausts... When the gas blows, it pushes the circular plate 37 away from the inside of the circular cover 31. When the circular plate 37 moves away from the inside of the circular cover 31, the gas is discharged through the gap between the circular cover 31 and the circular plate 37. After the exhaust pipe 2 has finished exhausting, under the extension and contraction of the spring 36, the spring 36 pulls the circular tube 35 to move closer to the inside of the circular cover 31. The circular tube 35 drives the circular plate 37 to move closer to the inside of the circular cover 31. When the circular plate 37 returns to its original position and enters the inside of the circular cover 31, the circular plate 37, together with the circular cover 31, once again covers the opening of the exhaust pipe 2 and continues to intercept external dust, thereby achieving dust protection for the exhaust pipe 2.
